Keystone, 'Safest Pipeline in the World,' Ruptures—Again

The Keystone pipeline—which carries hundreds of thousands of barrels of crude oil nearly 2,700 miles from the Alberta tar sands to refineries in Illinois and Oklahoma daily—was abruptly shut down Tuesday morning following a rupture in North Dakota, marking yet another accident along what proponents have called the "safest pipeline in the world."

South Bow, the Canadian company that manages the Keystone system, said it shut down the pipeline—which transports an average of around 624,000 barrels of crude oil per day—after detection systems sounded the alarm on a pressure drop. The company said the spill is confined to an agricultural field about 60 miles southwest of Fargo.

"The affected segment has been isolated, and operations and containment resources have been mobilized to site," the company said, according toThe Associated Press. "Our primary focus right now is the safety of onsite personnel and mitigating risk to the environment."

As the AP reported:

It wasn't clear what caused the rupture of the underground pipeline or the amount of crude oil released into the field. An employee working at the site near Fort Ransom heard a "mechanical bang" and shut down the pipeline within about two minutes, said Bill Suess, spill investigation program manager with the North Dakota Department of Environmental Quality. Oil surfaced about 300 yards (274 meters) south of the pump station in a field and emergency personnel responded, Suess said.

A proposed extension known as Keystone XL would have carried more tar sands oil—widely considered the world's dirtiest fuel—to refineries along the Gulf of Mexico. Opponents warned of the danger of leaks, with a 2021 report from the nonpartisan Government Accountability Office noting that there were 22 accidents along the conduit between 2010 and 2020. These include leaks of more than 100,000 gallons per spill in 2017, 2019, and 2022.

"Keystone's incident history illustrates the problematic pipeline's systemic issues," Bill Caram, executive director of the Pipeline Safety Trust, said in a statement Tuesday. "The Keystone pipeline appears to be on track to hit its average of about a significant failure every year. It's time to address this pipeline's shortcomings."

Following more than a decade of pressure from climate, environmental, Indigenous, and other groups, then-President Joe Biden revoked Keystone XL's permit on his first day in office in January 2021. President Donald Trump, who campaigned on a "drill, baby, drill" platform, now wants to revive Keystone XL.
